Is it "official Chase policy" that only purchases made with the Sapphire or Ink cards through the uR mall qualify for the extra points? I made a purchase from Hotwire using the Hyatt card and in response to my secure message I got the line that the Hyatt card does not qualify.

I know that people have been getting points using other cards, and I couldn't find anything in the T&Cs, although there is some slippery language that states "you will get a notification via e-mail after 3-5 days after checking out with your Chase card" or something like that.
